20090020425 | GAS SENSOR - The gas sensor includes a gas sensor element, a housing accommodating the gas sensor element, and an element cover fixed to the housing. The element cover includes an inner cover, and an outer cover. The outer cover is formed with outer openings at a side surface thereof, and includes a front end portion formed with a discharge opening, the discharge opening being located more closely to the front end side than the outer openings. The inner cover is formed with inner openings at a side surface thereof, the inner openings being located more closely to the front end side than the outer openings. When a clearance between the outer and inner covers at a longitudinal position of the outer openings is A, and an inner diameter of the outer cover at this longitudinal position is B, a ratio of A/B is set equal to or larger than a predetermined value. | 01-22-2009 |
20110100815 | GAS SENSOR - A gas sensor having a sensor element including: a plate-shaped solid electrolyte body; and a pair of electrodes sandwiching the electrolyte body. The electrodes include a measurement electrode portion, and a standard electrode portion disposed in an inner portion of the sensor element. A lead portion, which extends along the surface of the solid electrolyte body, is connected to the standard electrode portion. The standard electrode portion is mainly formed with a precious metal and contains a ceramic. The lead portion is mainly formed of a precious metal and has a ceramic content smaller than the standard electrode portion. A porous portion, which extends to the inner portion of the sensor element along the surface of the solid electrolyte body, has a gas permeability higher than the lead portion, is mainly formed with a ceramic, and is connected to the standard electrode portion. | 05-05-2011 |

20150355137 | THERMAL SHOCK RESISTANT GAS SENSOR ELEMENT - A thermal shock resistant sensor element that includes a sensor element having a gamma alumina coating on at least a portion thereof. The thermal shock resistant sensor element may be thermal shock resistant at temperatures greater than about 600° C. A method of making a thermal shock resistant element that includes plasma spraying gamma alumina onto a sensor element to form a thermal shock resistant element. The thermal shock resistant sensor element may be thermal shock resistant at temperatures greater than about 500° C. A thermal shock resistant sensor element that includes a sensor element having an alumina coating on at least a portion thereof. The thermal shock resistant sensor element may be thermal shock resistant at temperatures greater than about 500° C. and may demonstrate a Si poisoning resistance after exposure to the Gas Burner Test (850° C.) for at least about 60 hours. | 12-10-2015 |
20160187285 | GAS SENSOR ELEMENT AND GAS SENSOR - A plate-like gas sensor element extending in a longitudinal direction includes a plate-like composite ceramic layer which has an insulation portion having a through hole formed at a longitudinally forward end side and a solid electrolyte portion disposed in the through hole; an electrode portion disposed in contact with the solid electrolyte portion on a one-main-surface side of the composite ceramic layer; and a lead portion which is in contact with only the insulation portion on the one-main-surface side of the composite ceramic layer, whose forward end is recessed from the through hole toward a rear end side with respect to the longitudinal direction, and which is electrically connected to the electrode portion and extends longitudinally rearward. A rear end portion of the electrode portion overlaps with a forward end portion of the lead portion on the insulation portion on the one-main-surface side of the composite ceramic layer. | 06-30-2016 |
